International ClassA47K 1300ClaimsWhat is claimed is: 1. A method of fabricating a toilet seal (12) and cover (18) comprising the steps of; forming a seat (12) having a seat core (16) surrounded by a seat skin (14), forming a cover (18) having a cover core (22) surrounded by a cover skin (20), said method characterized by forming said cores (16, 22) of a waste material occupying a majority of the volume of the core and a carrier material occupying a minority of the volume of the core. 2. A method as set forth in claim 1 further defined as suspending the waste material in a polymer carrier to enhance the flow characteristics of the core closer to the flow characteristics of the skin than that of the waste material per se. 3. A toilet seat assembly comprising; a toilet seat (12) including a skin defining the exterior surfaces and a core disposed within and surrounded by said seat skin (14), a cover (18) including a cover skin (20) defining the exterior surfaces thereof and a cover core (22) disposed within and surrounded by said cover skin (20), said assembly characterized by said cores (16, 22) each comprising a waste material occupying a majority of the volume of the core and a carrier material occupying a minority of the volume of the core. 4. An assembly as set forth in claim 3 wherein said skins comprise a polymer and said waste material includes a mixture of a polymer as a carrier and a waste material suspended in the carrier. 5. An assembly as set forth in claim 3 wherein said waste material includes particles of wood suspended in a carrier polymer to define said core. |
